• Recent advances in data compression and voice<br />
coding have reversed the conventional wisdom<br />
about bandwidth.<br />
• It is now possible to transmit a digitized voice<br />
signal in less bandwidth than is required for an<br />
analog FM signal. This removes the last big<br />
obstacle to digital communication.<br />
• Digital system still tend to be more complex than<br />
analog, but large-scale integrated circuits have<br />
made it possible to build complex systems at low<br />
cost and in small packages.<br />
• Analog cellular radio can be seen as the first<br />
generation of wireless communication. Digital<br />
systems, are the second.
